Commissioning with the USS Peacock in 1836, William Ruschenberger sailed with
Edmund Roberts to Siam with the intention of winning a more favorable treaty
between the United States and "His Majesty the Magnificent King of Siam." The
treaty was signed, but Roberts died on the return voyage, leaving Ruschenberger
the task of chronicling the mission in a book he wrote titled, Narrative
of a voyage round the world, during the years 1835, 36, and 37 (London:
Richard Bentley, 1838). Ruschenberger pushed the advantage of his position
as fleet naval surgeon to join many naval expeditions and to seek out the
herbal pharmacopoeia of the tropics including a voyage in the 1850's to
Panama. On that trip he might have learned that curandango bark was removed
with a mallet, dried and used by native South Americans both as a cure for
syphilis and to kill rogue dogs, but it was in 1869 when Dr. Casares of Quito,
Ecuador used it to treat a case of cancer that the desperately ill imagined
a curative power surpassing the touch of religious faith. The public required
a government's protection from patent medicine salesmen and so the navy
directed Dr. Ayers, an assistant surgeon who was stationed in Peru, to collect
samples of the plant to add to the specimens that were sent by the Ecuadorian
government and distributed by the Smithsonian Institute. The following quote
is lifted from a fine antiquarian bookseller's catalog (Hertzmann, and
Margolis & Moss: 100 Books with Original Photographs
1846—1919; 2003):

After considering the testimonials, and some attempted cures in London and
Philadelphia that proved fatal, Dr. Ruschenberger states that "my investigation
of the subject leads to a conviction that there is much testimony but no
evidence that cundurango has a curative influence in cases of cancer.
